また、図４に示すように、バッテリ２４において取っ手部３４が設けられた他端面に対向する蓋部材２１の内面には、バッテリ２４の他端面（本実施形態ではバッテリ２４の取っ手部３４）に当接する突出部５０ａが設けられる。この突出部５０aは、バッテリ２４の回転を規制することで、バッテリ２４の抜けを防止する。なお、ここで、この図４は、バッテリ２４のうちの最も上方に配置されたものを示している。
そして、図５（Ａ）を参照し、突出部５０ａは、該突出部５０ａに向けて開放することになる取っ手部３４における上記連結部のコ字状の開放部に、バッテリ２４の軸線Ｃ１に沿って挿入されることで、バッテリ２４の回転を規制するものである。詳しくは、この突出部５０ａは、取っ手部３４における上記連結部に沿って比較的長く延在しており、バッテリ２４が回転しようとした際に、取っ手部３４の上記連結部のコ字状の開放部の壁部に当接することで回転を規制するものである。 Further, as shown in FIG. 4, the inner surface of the lid member 21 that faces the other end surface of the battery 24 on which the handle portion 34 is provided is connected to the other end surface of the battery 24 (in this embodiment, the handle portion 34 of the battery 24). A projecting portion 50a that abuts is provided. The protrusion 50 a prevents the battery 24 from being pulled out by restricting the rotation of the battery 24. Here, FIG. 4 shows the battery 24 arranged at the uppermost position.
Then, referring to FIG. 5 (A), the protruding portion 50a is formed on the axis C1 of the battery 24 at the U-shaped opening portion of the connecting portion in the handle portion 34 that opens toward the protruding portion 50a. The rotation of the battery 24 is regulated by being inserted along. Specifically, the protruding portion 50a extends relatively long along the connecting portion in the handle portion 34, and when the battery 24 is about to rotate, the U-shaped portion of the connecting portion of the handle portion 34 is formed. The rotation is restricted by contacting the wall portion of the opening portion.

なお、上記のような突出部５０ａは、通常複数のバッテリ２４に対応して同一のものを蓋部材２１に形成するが、本実施形態では、説明便宜上、突出部５０ａの形状と、異なる形状の突出部５０ｂ及び突出部５０ｃを、蓋部材２１に形成しており、突出部５０ｂは、突出部５０ａの下方に形成され、突出部５０ｃは、突出部５０ｂの後方に形成されている。そして、図１のｃ−ｃ線に沿う断面である図５（Ｂ）に、突出部５０ｂが示され、図１のｄ−ｄ線に沿う断面である図５（Ｃ）に突出部５０ｃが示されている。
